The Ruland Clamp style six beam coupling designed for precision coupling in light duty power transmission applications. Featuring 20 mm x 12 mm bores, this product ensures a zero-backlash connection that effectively reduces vibration, particularly beneficial for high-speed operations of up to 6,000 RPM. Constructed from premium 303 stainless steel, it not only delivers superior torque capacity but also enhances longevity through its robust construction methods rooted in North American sourcing. The innovative design incorporates two sets of spiral cuts, maximising performance while minimizing windup, making it an ideal choice for connecting servo motors to lead screws in various mechanical settings. Moreover, stringent manufacturing controls in Marlborough, MA, ensure that quality remains uncompromised throughout the production process, promising reliability and efficiency.
